ESA's human centrifuge at Medes in Toulouse, France.
The centrifuge that can spin volunteers to recreate gravity pulling towards their feet while laying down. Artificial gravity has potential to counteract some of the changes in the human body during space exploration.
Special exercise machines can be mounted on the centrifuges. The effect of centrifuge spinning alone is compared to spinning and exercise, and to control groups ,to prepare for exploration to the Moon and beyond.
